We will be clear.
The price of 13000 baths for a month is absolutely not the correct price, in total I spent more than 16000 baths for one month, the ad does not specify that internet is at the expense of the renter as well as water and electricity.
You have clearly overcharged me for the electricity bill which I find absolutely not normal.
Also, the place where is the apartment is not good at all, you have to take the high way all the time because it's far away from the center which increase the final bill to something like 17000 bht per month.
You can found way better apartment and localisation for the same price (17000 bht).
I don't recommand this airbnb for the price the localisation and the apartment.
